DISK FURROKW-OPENER.

Specification of Letters Patent.

Patented Nov. 21, 1 90 5.

Application filed December 16, 1904.. Serial No- 237,069.

To all whom it may concern.-

Be it known that I, EDWARD CI-IRISTMAN, a

citizen of the United States, residing at Louisville, in the county ofJefferson and State of Kentucky, have invented certain new and usefulImprovements in Disk Furrow-Openers, of which the following is aspecification.

My invention relates to improvements in disk furrow-openers forseeding-machines.

The object of my invention is to provide a disk furrow-opener of aconstruction which will be effectual in operation and also easilyassembled and capable of ready adjustment to the work to be performed.

My invention consists in the constructions and combinations of partshereinafter described, and set forth in the claims.

In the accompanying drawings, Figure 1 is a side elevation of a diskfurrow-opener embodying my invention. Fig. 2 is a sectional view takenon the line m in Fig. 1, the disk being shown in full lines. Fig. 3 is adetail ofa part of the grain-conduit. Fig. 4 is adetail view of aportion of the main frame and bearing to which the parts in Fig. 3 areto be attached. Fig. 5 is a sectional view on the line y g of Fig. 4.

Like parts are represented by similar letters of reference in theseveral views.

In the drawings, (t represents the disk, which is of the usualconstruction, which is mounted upon a suitable support or frame 6,attached to a drag-bar I) in the usual manner, by means of which it willbe connected to the main frame of-the machine. This main frame orsupport 5 is provided on one side with a recess 6 into which is adaptedto be fitted a curved arm 0 of the grain-cond uit 0. The grain-conduit 0may be of the usual construction, provided at its lower end with aforwardly-projecting shield or scraper 0 The recess 6 in the frame andthe projecting arm 0 of the conduit, which fits into said recess, arepreferably formed on a line approximately at right angles to the chordof the are which forms the front edge of the shield or scraper, if thesame is formed on a curve, and there is extended transversely across thearm a rib or projection 0 which fits in a corresponding depression orgroove 6 in the easing. The parts are firmly connected together by meansof bolts e and e, which pass through suitable openings d and 0 in therespective engaging parts. The bearing contact between the arm 0 and themain frame or support 7) is between the transverse rib a and the bottomof the groove 6 these parts being so formed as to leave a clearancebetween the other portions or plain surfaces of the arm and the recess.The recess 6 however, has a shoulder b on one edge thereof, againstwhich the edge of the arm is adapted to fit to form a more securefastening device and to relieve the bolts of the working strains.

It will be seen that by tightening the respective bolts 0 and a more orless the conduit 0, together with the shield or scraper carried thereby,can be adjusted to the proper position best suited to the work to beperformed and when so adjusted can be secured firmly in position andretained there, thus facilitating the work of assembling and alsofurnishing means by which the parts may readily be adjusted tocompensate for wear or for other purposes. The construction also permits the conduit and the shield or scraper to be readily removed orreplaced or renewed, if desired.

The construction described, it will be seen, forms a two-part frameadapted to be attached together by means which permit of adjustment ofthe parts, so as to bring the same in their proper working positions,irrespective of irregularities that may occur in the castings or inthedisks.

Having thus described my invention, I claim 1. In a furrow-opener, amain supportingframe formed in two parts, a furrow-opening disk mountedon one of said parts, a conduit mounted on the other part, a shield orscraper carried by said conduit, means for varying the inclination ofthe conduit in its relation with the vertical whereby the shield orscraper will be adjusted in its relation with the furrowopening disk.

2. In a furrow-opening device, a frame or support formed in two parts, adisk mounted on one of said parts, and a shield or scraper for said diskconnected to the other part, means for varying the relative inclinationof the said frame parts whereby the shield or scraper will be laterallyadjusted in its relation to the disk, substantially as and for thepurpose specified.

3. In a furrow-opener, a supporting-frame formed in two parts, a diskmounted on one of said parts and a shield or scraper for said disk onthe other part, a fulcrum on one of said parts, an adjustable fasteneron-eaeh side of said fulcrum whereby the position of one of the partsmay be varied in its relation to the vertical to permit a relativeadjustment of the shield and disk, substantially as specified. at. In afurrow-opener, a supporting-frame in two parts, a disk mounted on onepart and a conduit on the other part, a fulcrum or projection on one ofsaid parts adapted to contact with the other part, and adjustablefastening means on each side of said fulcrum whereby the position of theconduit may be adjusted with reference to the disk, substantially asdescribed.

5. In a furrow-opener, a supporting-frame formed in two parts, one ofsaid parts being provided with a recess and the other with an arm to fitin said recess, a transverse bearing between said parts, adjustablefastening means on each side of said transverse bearing, a disk mountedon one of said parts, and a conduit carrying a shield orscraper on theother part, for the purpose specified.

6. In a furrow opening device, a two-part supporting-frame, a diskmounted on one of said parts, a conduit carrying a shield or scraper onthe other part, one of said parts being formed with a recess and theother with an arm fitted into said recess, a transverse bearing betweenthe respective parts, adjustable fastening devices on each side of saidtransverse bearing, whereby the conduit may be adjusted with referenceto the disk.

7. In a furrow-opening device, a two-part supporting-frame, a diskmounted on one of said parts, a shield or scraper for said disk mountedon the other part, a transverse bearing having a fulcrum between therespective parts of said two-part frame and adjustable fastening meanson each side of said transverse bearing whereby said shield or scrapermay be adjusted to or from said disk and held in proper relationthereto, substantially as specified. I

8. T he combination with amain supportingframe, a disk journaledthereon, a conduit carrying a shield or scraper, an arm on said conduitand a recess in said frame into which said arm is fitted, a rib on oneof said parts and a groove in the other part, fastening devices on eachside of said rib and groove, and means for adjusting said fasteningdevices to produce adjustment of said conduit with reference to saiddisk, substantially as specified.

In testimony whereof I have hereunto set my hand this 12th day ofDecember, A. D. 1904.
